代码说明:

  gmm模型下的语音情感识别系统,GMM只是一个数学模型,只是对数据形态的拟和,但是和你所看到的数据分布存在出入也是正常的,因为用EM估计GMM的那些参数时,一般假设我们所得到的数据是不完备的(也就是说假设我们看到的数据分布不是真正的分布,它在运算时把那部分丢失或者叫隐藏的数据“补”上了)(gmm model speech emotion recognition system, GMM is a mathematical model, but fitting the data form, but you can see there is access to the data distribution is normal, because those with the EM estimated GMM parameters, the general assumption we get the data is incomplete (that is, assuming we see the distribution of the data distribution is not real, it is part of the operation at the time that is lost or hidden data is called " fill" on the))

    这是基于隐马尔可夫模型的连续语音识别代码,不同于dtw,这是个完整的工程,我把需要的voicebox也放进去了,一共用到9个子函数,包括模板的训练算法何识别算法,是完全可以使用的。(This is based on the hidden Markov model of continuous voice recognition code, different the dtw, which is a complete project, I need to put the voicebox into a total of nine sub-functions, including the template training algorithm to identify the algorithm, Is fully available.)
